Les, You gotta stop messing with those old technology batteries that leak acid -- especially in the DeLorean where they get a lot of shock and vibration being near the rear suspension. Steve Wynne of DMC Houston told me that the reason why passenger side carpets are hard to come by (compared to the availability of the driver's side) is because so many of them get damaged by leaking battery acid. Unfortunately for my car, it came from its previous owner with plenty of battery acid damage. I get only Optima brand batteries now. They can't leak, work in any position, don't accumulate explosive gasses and are not subject to damage from vibration like the antique batteries sold at K-mart. Other cars are not as critical for battery quality. If one leaks in an engine compartment, it really doesn't matter so much. If it explodes, it is under the hood -- not with you in the passenger compartment. Before I used to really like K-mart batteries, but the guys who worked there always warned me that if I put too big a battery in my car that it would overload my electrical system and burn it out. If I put a 850CCA battery in a car that their books said only needed a 550CCA, then they threatened that if the battery went bad then they would not honor the warranty. (For those of you who don't know batteries, theses guys were completely wrong!) I put up listening to this nonsense for several years and from several different guys that worked there. Also be aware that battery warranties (with the exception of Optima) are ALWAYS longer than the manufacture expects them to last. This is to keep you coming back to pay for a new battery (of their brand) that are prorated. Since Optima is so much better than the rest, they don't need to keep you coming back by selling you a warranty that is going to out live the battery.
